Ms. Erin had 25 students in on of her math classes last semester. Now this class has 22 students. What is the percent of change? 10%13.6% 12%

12% decrease

Step-by-step explanation:

[(new value - old value) / old value] x 100

(22 - 25) / 25 = -3/25 = -0.12

-0.12 x 100 = -12%

when you have a negative it indicates a decrease rather than an increase

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
